Specification of Letters Patent.

Application filed December 14, 1914. Serial No. 877,210.

To all whom it may concern:

Be it known that I, WILLIAM B. Dmvnn- DORF, a citizen of theUnited States, residing at Sprakers, in the county of Montgomery,-

State of New Yorkyhave invented certain new and useful Improvements in Dirigible Lamps for Automobiles, of which the-fol- ..owing is a description, reference being had to the accompanying drawings, forming a part hereof.

'My invention relates to ne w and useful improvements inadjustable head-lights for automobiles and other forms ofvehicles, and has-for its object to provide a simple and durable device in which. the head-lights are automatically shifted to cast their light on the road over which'thesteering wheels-are set to travel, and also to provide means whereby the lights may be shifted by lever mechanism independent of the steering gear to ,throw their light in different directions.

My invention comprises various detail construction, arrangements of parts and combinations ofa character to form improvements in construction and operation over that shown and described in my Patent No. 1,079,844, and will be fully described, shown in the drawings and finally claimed.

Similar numerals of reference indicate 1 corresponding parts in the several'figures of the drawings, in which- Figure 1 is a side view partly broken away of an automobile with. my attachment in place. Fig. 2is a plan view of my attachment showing parts of the automobile. Fig. 3 is an enlarged perspective view of my attachment. Fig. 4 is an enlarged vertical section of the operating lever. Fig. 5 is a perspective view of the lower end of the lever to more fully illustrate the manner inwhich the operating rod is gripped by the lever. Fig. 6 is a detail perspective view of the locking dog at the lower end of the lever.

Reference now being had tothe-details of the drawings by numerals, 1 indicates the body, 2 the wheels, 3 the frame, 4 the steering wheel, 5 the steering post, .6 the horizon-v tally disposed rock shaft, having the depending arm 7. To the lower end of said arm 7 is secured the rear end of the connect ing rod 8, which is secured at its forward end to an arm 9 projecting from one of the steering knuckles 10'10 of any preferred form of automobile.

p The usual connection rod 11 is mounted at? lts ends on projecting arms 12--12 of the" knuckles 10,, thus causingfthe steering wheels to operate simultaneously.

' Patented Aug. 24, 1915.

, All of the above named parts are -of.a well 1 known character and form no part. of this invention. Secured to the frame 3, as. shown at13, are lamp bracket post sockets 14, in'which are mounted for horizontal rotation, the lamp bracket posts 15 havingat' their upper ends lamp forks 16 on which the lamps 17 are mounted, one lamp only being shown in place in Fig.1. Secured to arms 18 projecting from the lamp forks, is a rod 19, said rod being in two parts connected by a turnbuckle 20 which provides for adjustment of the lamps in relation to each other and provides means for transferring movem nt of one lamp to the other. Mounted on the lower end of the post 15 on the side of the automobile on which the arm 7 is located, is a laterally'extending arm 21,- to the outer end of which is pivotally secured the-forward end of a lamp operating rod 22, the rear end of said rod 22 being mounted to normally slide freely through a perforation in the lower end of a hand operated lever 23.

A swing arm 24 mounted at 25 on the frame or other'convenient part of the autosaid connection is a flexible connection and one in which the rod 22 may be moved either forwardly or rearwardly by the arm 24, but

1 same into convenient reach of the operator.

The lever 23 has a central bore 34 anda rod 35 is mounted therein for short "vertical movement. A coil spring-36 arranged between the upper end of the'lever 23 and a press button 47 secured to the upper end of the rod 35,.tends to hold the rod 35 in' its upper position.

Secured to the lower end of rod 35 in any preferred manner is-a bolt 37, said bolt being of a width suflicient to extend entirelythrough from side to side of the lever 23, which prevents its turning therein, said bolt 37 being mounted for a slight vertical movement in a cutaway portion 38 formed at right angles immediately above the opening 29 through which the *rod 22 extends and is in communication therewith.

The bolt 37 is tapered to a reduced lower end, as shown at 40, for engagement with the notches 41 formed in the upper surface of the rear end of rod 22.

The bolt 35 is further provided near its upper end on'one edge with a lug 42 adapted to engage a notch 43 in a segment 44 mounted on the automobile frame, said lug 42 and notch 43 when in engagement, being adapted to hold lever 23 firmly in an upright position.

It will be noted by reference to Fig. 4

that the lo wer surface of the opening 39 through which the rod 22, under certain conditions, adapted to slide, is convex or rounded, as at 45, and the upper surface of said opening, as shown at 46, is slightly cut away. This is 'to provide a slight clearance so that whenthe bolt 37 is forced down to grip the rod 22, and the lever 23 is swung forwardly or rearwardly, there will be no tendency of the parts to bind and bend the rod 22 up or down, owing to the fact that the said rod gripped between two edges on which theigrod may roll, and still be held firmly against any longitudinal movement thereon.

By the construction shown, it will be seen that in steering the vehicle, the arm 7 is swung and through connecting link 31, the arm 24 will be swung and the springs 27 being of a proper'strength, rod 22 will be moved, thereby swinging the lamps in the direction desired. At this time, the rear end of rod 22 will slide freely through the opening 39 in the lever 23.

Should for any reason the operator desire to swing the lamps independent of the above per surface of rod 22, and by swinging the vlever 23 against the tension of one of the springs 27, the lamps will be moved asde- I sired.

If the steering mechanism has not been changed during the independent operation of the'lamps by the lever 23, the operator by permitting the lever 23 to come to a vertical position, said movement being assisted by the spring 27 which is under tension, and releasing the pressure on button 47, the rod 22 will be maintained-in a vertical position by lug 42 re'ntering notch 43.

Should a change in the steering mechanism be made while the lower end of lever 23 is gripped to the rod 22, and the operator desires no further independent movement in the lamps, may release his hold on the lever 23 and button 47, at which time the lever is left to swing with the automatic mechanism with the lug 43 riding on the smooth edge of the segment 44 until said lug 42 comes into alinement with notch 43, when spring 36 will cause said lug to enter .the notch and release the rod 22, thereby leaving the lever in an upright position and convenient to the'operator the next time he wishes to use it.

Having thus described my invention, what I desire to secure by Letters Patent and wish to claim is 1. In combined automatic and manually operated dirigible lights for vehicles, rotary lamp carrying posts connected for simultaneous movement, an arm extending laterally from one post, a longitudinally movable rod secured to the arm,a swinging arm mounted on the vehicle with its free end slidably connected to the rod, springs encircling the rod.

on either side of the swinging arm having stops at their outer ends secured to the rod, an adjustable link connecting the swinging arm and -a longitudinally movable part of the steering mechanism, and a manually operated lever having means for make and break connection with the longitudinally movable rod.
